    Description

      This is for book keeping all the work that is being done to submit the Lustre client for acceptance into the Linux kernel. Alongside the tickets below, there are a few major areas that need to be addressed before the client can be submitted.

      Lustre Upstream Client Requirements

      • Finish IPv6
      • Finish checkpatch.pl cleanups
        • Space -> Tabs
        • SPDX headers and other warnings
        • Update checkpatch.pl script in Lustre tree (it hasn't been updated since 2017)
        • Remove errant kernel-doc comments
      • Remove procfs from client
      • Remove libcfs (except for kernel compatibility)
        • Convert cfs_hash -> rhashtable
        • Remove custom interval tree
        • Move from custom debugging -> slightly less custom debugging
      • Ensure various Lustre sanity tests pass
      • Clearer separation of client/server using HAVE_SERVER_SUPPORT
      • Unify Lustre modules to just lnet, k*lnd, lustre
      • Decide on o2ib submission
        • Port o2ib driver to nicer APIs favored by Infiniband maintainers
        • Delay submission of o2ib until later
        • Determine how to support GDS out-of-tree
      • Decide on how to submit code upstream
        • Port each individual change (large patch series)?
        • Fresh port of client to latest Linux (couple small patches)?
      • Decide on processes for maintaining upstream client alongside out-of-tree code
        • Develop automation (along the lines of Neil Brown’s script) to generate a port of the client to the kernel
        • Develop automation to find patch that are missing out-of-tree vs. in-tree
        • Will the client be built for kernels that already have a Lustre client?
        • How will servers be built for kernel with the Lustre client?
